That’s not because it’s decentralized or open, it’s because it doesn’t matter. If it was larger or more important, it would get run over by bots in weeks.

Any platform that wants to resist bots need to - tie personas to real or expensive identities - force people to add AI flag to AI content - let readers filter content not marked as AI - and be absolutely ruthless in permabanning anyone who posts AI content unmarked, one strike and you are dead forever

The issue then becomes that marking someone as “posts unmarked AI content” becomes a weapon. No idea about how to handle it.

Usenet died partly due to the ads, and the inability for adblocking software at the time to keep up.

People left and never came back.

But those bots were certainly around in the 90s

Of course - because everyone is banned upon first suspicion.
